FREMONT — A 22-year-old man was killed early Sunday when his car veered off Interstate 880 and rolled down an embankment, the California Highway Patrol said.

Details remained sketchy Monday as to what exactly caused Hernaldo Sequeira of Fremont to lose control of his Mercedes 300E on the freeway about 3:30 a.m., CHP Officer Jeff Moring said.

Witnesses told officers that Sequeira, whose identity was released Monday by the Alameda County Coroner’s Bureau, was driving about 100 mph northbound on the freeway when he drove off the North Fremont Boulevard off-ramp and his car tumbled into a ditch, Moring said.

It was unclear Monday if Sequeira was ejected from the vehicle, the officer said. The coroner’s bureau was scheduled to conduct an autopsy Monday, but Sequeira’s cause of death was not available, coroner’s spokesman Sgt. Riddic Bowers said.

The crash led officials to close the off-ramp for about three hours, CHP Officer Gabriel Potter said.

Intuitive Surgical paid $30.4 million in cash on March 5 for a more than three-decade-old building about two blocks from its current headquarters, which are on Kifer Road in Sunnyvale, according to Santa Clara County property records.

House Oversight and Government Reform Committee Chairman Elijah Cummings, D-Md., said in a letter sent Thursday to White House Counsel Pat Cipollone that the administration has failed to produce documents tied to Kushner and other officials despite requests from the committee since 2017.
